The Startup Fuel adder is accessed in the same way as the REVXtender. Hit CTRL-F when connected and the motorcycle running. there are 2 boxes one for Rev Xtend and one for Startup Fuel Add. The go under Tools and there is a new options called adjust startup fuel or something like that. it will bring up a box with 2 settings, amount of fuel to ADD or SUBTRACT and for how many revolutions when starting the bike.

 

The startup fuel is really for big builds that are hard to start. If it works for you, thats cool. Mine starts right away as it sits, so I don't need that one.

It's the accelerator pump that I am fooling with. It adds some extra fuel when you twist the throttle. Hopefully I'll gain a few MPG. Now if I can just keep it under 80mph I'd be doing real well.

 

Mine starts up right away but with this feature turned on it starts up even easier.
